To all cello/m. it' may concern:

Be it known that l @scan ji. nnsrnsos, a citizen oi the United rotates,residing at Chicago, in the county of Coeli and State ot illinois, haveinvented certain new and use'lul Improvements in Lamps, of which the'lollowing is a specification.

This invention relates` more particularly to lamps adapted to be usedtor burning gt iolene or otherl liquids which are to be volatilized, butsome oi tl'ie ieatures may be applicable to other types ci lamps. ltsobjects are to provide an improved 'l'orin oi lamp with the parts soarranged and constructed that they may be conveniently assembled, andwhich will be etiicient and durable in operation. l attain these objectsin the device or apparatus shown .in the accompanying drawings inwhich-n ll'igure 1 an elevation showing a prelerred 'torni oi my device,with parts broken away to show the interior construction; Fig. 2 is asectional view ot the generator' tube taken on line 2 2 of Fig. 1 ,z andFig. 3 is a detail showing a portion ci the globe and globe-holder.

As shown in the drawings, represents the lamp as whole, which comprisesa suitable trame, generator, burner, etc. At the top of the i'rame is aY or three-way 'litting 5 which has a tapered hole 6 in the top thereoiIto receive tapered and shouldered connection 7 which connects with theleed pipe 8. The connection 7 is drawn down into the hole I to 'form atight i'it, by means of a nut Q which engages with the shoulder ci saidconnection. The two lower stems of the iitting are also provided withsimilar connecting devices, one ci said branches being closed while theother branch is provided with a passageway 1l) which allows the liquidto pass into a tube 11 which forms a portion oi the lamp iii-aine. Thetube 11 is bentnear the bottom and connects at its lower end with a tee12 which has a passageway therethrough leading to a valve 13. This valveadmits the liquid to the generator tube 14 which contains suitable means'lor ditlusing the Vfluid so that it may be generated into gas. l pre-'ler to place in this tube a rod or core 15 or' suitable material,either' absorbent or nonabsorbent, and wrap around this rod or core wiregauze 16 which lits closely within the space between said core or rodand the inner walls ol the tube 14.

While l have ound that asbestos rope wrapped in annealed brass gauzeprovides an ei'licient distributer for the generator, T am also awarethat other materials may be used for this purpose.

The generator tube 14 connects with a tip 17 which is countersunl; toreceive said tube; and in order to prevent the core 15 or the gauze 16from being Aforced into the tip to close the same, l insert a shortsection of sprin 18 between the tip and the ends of the rod and gauze,which etlectually prevents such closure. The outlet orifice 19 ol thetip 1.7 is counter-sunk or enlarged at the outer end to facilitatecleaning the saine. As such tips occasionally become clogged, it isnecessary to insert a wire into the orilice to disn lodge anything whichmay have stopped therein. As this wire is preferably inserted throughone of the holes 2O which admit air into the tube 21 leading to, or'forming a part oi' the mixing chamber, it would ordinarily be ditlicultto direct the end ot the wire into the small opening 19; but when thesame is countersunk as shown, the wire will be readily directed into theorifice. The tube 21 connects with a tee 22 which has a passagewayconnecting with a tube 23 which also forms a part ot the lrame and iscurved at the lower end to connect with a fitting 24 which supports theburner. The frame is completed by a second curved tube or rod 25 whichconnects with the blind ends of the tee 12 and the fitting .24 andcorresponds in appearance with the tube 23; and an upper top memberwhich connects with the blind end oit the tee and is drawn up intoengagement with the Y 5 by means oi a tapered litting as abovedescribed, this branch corresponding in appearance with the tube 11. Theiitting 24 is provided with a drain 27 and is shouldered at the top toreceive a sleeve 2S 'forming the bottom portion oi the burner. Thissleeve is also shouldered to receive the globe-holder 29 which issecurely held in position by a second sleeve SO which hts tightly overthe tapered upper end of the sleeve 28. This latter sleeve is adapted toreceive the cap which holds the mantle; but as this cap and mantle lormno part oi' the present invention, they are not shown.

The globe-holder is or a novel form oi con struction and comprises a hatdisk portion having holes 31 lor admitting air to the globe and having achannel 32 formed around the periphery thereof to receive the hangedbottom of the globe 33, the arrangement being such that the bottom edgeof the iiange rests in the bottom of the channel, while the outer laringedge of the holder also supports the body or the globe 33. rlhis devicewill securely hold the globe while at the same time resenting littleobstruction to the light and aving no unsightly prongs extending uparound the sides of said globe. The Y 5 a so supports a bell 34, bymeans of a chain 35, as indicated.

When the lam is to be started, the Valve 13 is opened to a( mit a smallamount of gasolene to the generator' 14 which is first heated by meansof an alcohol swab or the like. The gas thus generated passes outthrough the orifice 19 where it is mixed with air which enters throughthe openings 20, and the mixture thus formed passes down through thetube 23 to the burner where it is ignited. After the burner is lightedit will keep the generator tube heated, and the flow of gasolene orfluid may be regulated by means of the Valve 13. The gauze 16 is ofconsiderable advantage, as it tends to difuse the asolene around in thetube 14 Where it W' l become quickly heated and at the same time pre-Vents the gasolene from passing too freely through the tube.

Having thus described my invention,

which I do not wish to limit to the exact details of construction hereinshown and described, what I claim and desire to secure by Letters Patentis- 1. In a generator for lamps, the combination of a tube, a core orrod of noncombustible material in said tube, a strip of wire gauze woundaround said rod and filling the space between said rod and the innersurface of said tube, a perforatedtip for said tube, and a springinterposed between the end of said rod and said tip to prevent said rodfrom closing said perforation or abutting against said tip.

2. In a generator for lamps of the character described, the combinationwith a tube leading from a source of supply, of a Valve for controllingsaid sup ly, a tube engaging with said Valve, a nona sorbent rod or corein said tube, a reticulated metallic diffusing member lling the spacebetween said rod and said tube, a perforated cap at the opposite end ofsaid tube, and a spring for preventing said rod from abutting againstsaid cap.
